Capable of monitoring flow through open channels, partially full sewer pipes, and surcharged pipes without flume or weir, MantaRay uses submerged, hydrodynamically shaped ultrasonic sensor that sheds deposits and stringers to promote reliable operation. Flow rate and total are displayed and logged in real-time, and power can be supplied via built-in, rechargeable batteries or external 12–24 Vdc batteries. Included battery charger allows continuous operation with 4–20 mA and relay outputs.

For accurate flow measurement of wastewater, sludge, slurries, chemicals, and abrasives, PDFM 5.1 employs Doppler signal processing with ability to filter out noise. Product shows flow rate instantly once ultrasonic sensor is mounted on outside of metal or plastic pipe and can be used for flow troubleshooting, spot checks, or balancing flow. After operator enters pipe diameter, unit will display, totalize, and log data in choice of gallons, liters, or any other engineering units.

Able to measure flow from outside pipe, DFM 5.1 uses doppler signal processing technology and works with difficult liquids, such as wastewater, sludge, slurries, and abrasives, or any liquid with bubbles or suspended solids. Clamp-on ultrasonic sensor mounts on ½ in. ID or larger pipe, and calibration and start-up are facilitated via 5-button keypad. Standard features include backlit display and totalizer, isolated 4–20 mA output, and 6 control relays. Several options are also available.

Able to be calibrated to channels of any shape in municipal stormwater, combined effluent, raw sewage, and irrigation water applications, AVMS 5.1 uses 3 submerged ultrasonic sensors to continuously measure velocity at different points. One of those 3 sensors may also monitor water level, or separate non-contacting ultrasonic level sensor may be used in system. Forward and reverse flow can be measured, and sensors are resistant to fouling and corrosion. Built-in data logger is optional.

Equipped with non-contact ultrasonic sensor, PSL 5.0 is suitable for sewage lift stations, wet wells, and storage tanks. Users can also connect loop-powered pressure sensor for redundant sensing in applications with foam or grease. Controller will continuously recalibrate pressure sensor and automatically switch back and forth from ultrasonic to pressure sensor as required. In addition to isolated 4-20 mA output, PSL 5.0 provides 6 programmable control relays and automatic pump run time logging.

Intended for use in treatment plant headworks, DLT 2.0 can measure differential level at barscreen as well as open channel flow through flume. It works with 2 non-contacting ultrasonic sensors: one installed upstream from barscreen, and another installed downstream for differential level control. It is also possible to install second sensor in flume to also measure flow. Along with backlit LCD, features include relays for barscreen rake and level control as well as three 4-20 mA outputs.

Designed for measuring clean liquids like water, oils, and most chemicals, Portaflow PT500 Transit Time Flow Meter works with any plastic or metal pipes from 0.51-78 in. OD, and can be used for troubleshooting, spot checks, and balancing flow. It features backlit graphics display, 4-20 mA output, data logger, RS232 and USB outputs, and OS with quick start calibration menu. Operating 16 hr on internal battery, unit can store calibrations for up to 20 different sites.

Tank Farm Level System leverages Windows(TM) TFS Tank Farm Supervisor software, which lets operators supervise tank fills/discharges and monitor tank farm inventory from one central location. Able to concurrently monitor up to 32 tanks, system can also automate daily or work shift inventory logging; individual tank levels data will be logged at programmable intervals on PC's disk drive. Also, tank levels and control relay status are continuously displayed at each tank and monitoring PC.
